Application led November 7, 1913. Serial No. 799,684.

T0 all whom 'it-may concern:

Be it known thatV I, JOHN F. NETTLE, a citizen of the United States, and aA resident of Butte, in the county of Silverbow and State of .Montana, have invented a new and Improved Resilient Wheel, of which the foli flowing is a full, clear, and exact description.

This invention relates to improvements in resilient wheels, and has for an object to provide an improved structure wherein the resilient effect of a pneumatic cushion is provided without liability of puncturing ofl lprovided with a plurality of bores on the periphery,vthe bores preferably extending at a tangent and designed to receive a cushioning member, as for instance a pneumatic ball, and also the end of a reciprocating shoe, 'whereby the shoe is resiliently supported when the wheel is in use. A `pair of side plates are provided for properly holdin the shoe in place, and also the various ba ls so that there will be no movement of the respective parts except a proper reciprocation of the shoes.

In the accompanying drawing-Figure 1 is a side view of a wheel embodying the invention, certain parts being broken away for better illustrating the construction; Fig. 2 is a section through Fig. 1 approximately on line 2-Qg Fig. Bis a view similar to Fig. 2,

but disclosing a slightly modified form of the invention.

Referring to the accompanying drawing by numeral 1 indicates a hub, and 2, spokes connected therewith, and also with felly 3. The felly 3 is of special construction. Con nected with felly 3 are side plates 4 and 5 held against separation at the periphery by suitable bolts 6. Arranged in felly 3 are a Speoieation of Letters Patent.

plurality of bores 7 extending at a tangent, said bores extending from the peripheryl of the felly inwardly, and each pair having arranged therein a pneumatic cushion 8 in the form of a ball. The ball of course is hollow, and may be supplied with air or gas of any desired kind without departing from the spirit of the invention. Resting on the respective balls 8 are reciprocating members 9 provided at their outer ends with feet 10, the outer' face of the feet 10 being struck on the arc of a circle so that all of the feet taken together form substantially a continuous surface, as shown in Fig. 1. The body of each of the reciprocatin,r ,1r members 9 is formed with shoulders 11 designed to rest against retaining straps 12 secured to the felly in any desired manner. The extreme outer edges of the side plates 4 and 5 bent over at 13 and 14 for engaging the shoulders 11, as clearly shown 1n Fig. 2. By this structure the reciprocating members 9 may be moved inwardly when in the position shown in Fig. 1, but cannot move outwardly from such position. I'Vhen the wheel is in use these members will successively move inwardly and collapse to a greater or less extent,pthe balls 8. As soon as the wheel is turned over so that the respective reciprocating members are released the cushioning members 8 move thc-members 9 back to the position shown in Fig. 1.

In Fig. 3 will be seen a slightly modified form of the invention in which balls .5 and 16 are arranged in each of the bores 7 whereby' a greater cushioning effect is produced for the reciprocating member 9.

What I claim is- In a resilient wheel of the character described, a felly formed' with a plurality of bores arranged at a tangent. each bore having an appreciable depth and having straight side walls, a pneumatic ball in each of said hores, a plunger arranged in each of said bores-and resting against said balls, cach of said plungers being formed with bearing sides engaging the side walls of said bores so as to be guided in a reciprocatory movement thereby, each of said plungers being also formed with shouldered portions. a pair of side plates rigidly secured to' said felly, said side plates being formed with overa re Q mamme .hanging perpheral edges engaging certain of said shoulders, and a retaining pate a1- ranged between respective plum ers overhanging other of said shoulders, W ereby the 5 phmgers are limited in their outward move.-

ment.

n testimony whereof I have signed my name to this speccaton in the presence of two subscribing witnesses.
